Application filed Octobeii22, 1908. Serial No. 458,997.

To all whom it may concern:

lBe it known that we, DENNIS J. MENTON and HENRY WIECHMANN, citizens ofthe United States, residing at Richmond Hill, in the county of Kings andState of New York, have invented certain new and useful ImprovementsinSectional Cesspools; and we d0 declare the following to be a full,clear,

as will enable others skilled in the art to which it appertains to makeand use the same.

This invention relates to new and useful the body'and dome areconstructed of a plurality of tongued and grooved plastic sections;andto provide a cess pool wherein the parts or sections comprising thesaine and especially the dome may be readily assembled.

The secondary object oi' the invention is to provide a simple anddesirable cess pool at last indefinitely. l

'Vith these and other objects in View, the

construction, combination and arrangement of parts, as will be moreiully described and particularly pointed out in the appended claim.

Inthe accompanying drawings, Figure -1 is rovements shown in position inthe ground lig. 2 is a lan view thereof with one of the sections orlocks comprising the dome omitted. Fi 3 is a central verticallongitudinal section 3 ig; 4 is a horizontal section taken of the domesections.

In the embodiment illustrated, the cess pool` comprises a cylindricalbody l, and a receive the discharge pipe 4. Tie body of the pool isformed by a plurality of cylin drical sections 5 placed one upon'theother, each section being formed by a plurality of building blocks 6which aie provided with coperating tongues and grooves 7 and 8,respectively, and which may be peiitorated to permit the sewerage -todischarge therethrough into the ground surrounding the body.

'.jhe dome l is formed by a plurality of tongued and grooved sections 9which are, of concaveform in vertical section and arcuate forni inhorizontal section, each ofthe sections being provided in `its .loweredge With an' approximately Vesbaped recess 1.0 to receive the inner topedge ofthe upper or top section 5 of the pool body. rihe dome sectionsare also formed with cooperating tongues and grooves 11 and 12, which,however, as will be particularly observed, eX- tend trom their top edgesonly apA roxiinately one-half their heights in order t at the sectionsinay be pressed outwardly from the iiiside to the position indicated in.dotted lines in FigjQ, when all except the last section have beenassembled in order to provide for the insertion or placing in positionof the la st sectipn, the. V-shai'ed recesses holding the lower ends ofthe vdome sections against dis- )laceineut during this operation. ltalso to e observed that the construction an( finanner in which the domeis arranged in position is such as to enable the same to standconsiderable pressure' without` giving away, which may be caused byavehicle passing over the ground or surface at the point where the cesspool is located.4

From the foregoing description, taken in connection with ltheaccompanying drawings the construction and operation of the inventionwill be readily understood without requiring a more extendedexplanation- Various changes in the forni, proportions and the minordetaiis of construction may be resorted to Without departing from theprinciple or sacrificing any of the advan- V tages of this invention asdefinedin the appended claim. f

Having thus described and ascertained the nature of our invention, whatwe claim as new and desire to secure by Letters-Patent is: A cess poolof the character described, comprising a .cylindrical body formed of aplurality ci tongued and grooved sections and a dome having a centralopening, formed oi a plurality of blocks provided in their bottom edgeswith receieses to reccxe th inner set 01.11' harid in presence of twosubscribing upper odge of the top sev/Lum o1Y the cess pool 'gWMmesx-QS.
